This cultivar forms a medium size (16 inches high by 41 inches wide) mound of corrugated, thick textured foliage and near white flowers from late June into July. The flowers have a pale lavender stripe in the middle of the petals. It is a slow growing cultivar that was registered in 1984 by The American Hosta Society.

H. 'Gold Medallion' is a sport of H. 'Tokudama Aureonebulosa' that was found in tissue culture production.

The Hostapedia by Mark Zilis (2009), states that this cultivar "...has been around for many years under an assortment of names including H. tokudama 'Golden' and 'Golden Tokudama'. Both of those names have also been used for the very, very similar 'Golden Bullion'."

The New Encyclopedia of Hostas by Diana Grenfell (2009) states: "Group name embracing all yellow-leaved natural sports of H. 'Tokudama'...Site in light to medium shade all day, otherwise the edges can scorch. Among the first yellow-leaved hostas introduced. Now largely superseded by gold-leaved hostas which do not scorch."

Nomenclature changes recommended in the 1991 book The Genus Hosta by W. George Schmid and accepted by The American Hosta Society would update names as follows: H. tokudama is now H. 'Tokudama'.

"Plant is a yellow sport of H. 'Tokudama Aureonebulosa'. Several clones exist and form the H. 'Tokudama Aureonebulosa Yellow' group. This clonal cultivar name has been assigned and is horticulturally used for all yellow-leaved members of the H. 'Tokudama Aureonebulosa' group but this is technically incorrect because several distinct forms of the latter exist. I have established a H. 'Tokudama Aureonebulosa Yellow' group...under which all the distinct yellow taxa in this group can be assembled in a broad sense and named."

An article by Marvin C. Eisel, Hosta Registrar in The Hosta Journal (1985 Vol. 16) states that, "In the Fall 1984 The American Hosta Society Newsletter, page 12, I reported that I had registered in the name of The American Hosta Society, the cultivar name 'Golden Sunburst' for the golden forms of H. ' Frances Williams' and 'Golden Medallion' for all the golden mutations of H. tokudama."
